For applications where variable speeds are necessary, typically an AC motor with an Inverter or brush motors are used. Brushless DC motors are an advanced option because of their wide quickness range, low warmth and maintenance-free operation. Stepper Motors offer high torque and easy low speed operation.
Speed is typically managed by manual procedure on the driver or by an exterior switch, or with an external 0~10 VDC. Speed control systems typically utilize gearheads to increase output torque. Gear types range between spur, worm or helical / hypoid based on torque demands and budgets.
irrigation gearbox Mounting configurations vary to based on space constraints or style of the application.
The drives are high performance and durable and feature a compact and lightweight design.
The compact design is manufactured possible through the combination of a spur/worm gear drive with motors optimized for performance. That is accomplished through the constant application of aluminum die casting technology, which ensures a high degree of rigidity for the gear and motor housing at the same time.
Each drive is produced and tested specifically for each order and customer. A sophisticated modular system allows for an excellent diversity of types and a optimum degree of customization to client requirements.
In both rotation directions, described end positions are guarded by two position limit switches. This uncomplicated option does not only simplify the cabling, but also can help you configure the end positions quickly and easily. The high shut-off accuracy of the limit switches guarantees safe operation shifting forwards and backwards.
A gearmotor delivers high torque at low horsepower or low velocity. The speed specs for these motors are normal speed and stall-acceleration torque. These motors make use of gears, typically assembled as a gearbox, to lessen speed, making more torque available. Gearmotors are most often utilized in applications that require a whole lot of force to move heavy objects.
By and large, most industrial gearmotors use ac motors, typically fixed-speed motors. Nevertheless, dc motors may also be utilized as gearmotors … a whole lot of which are found in automotive applications.
Gearmotors have several advantages over other types of motor/gear combinations. Perhaps most of all, can simplify design and implementation by eliminating the step of separately developing and integrating the motors with the gears, hence reducing engineering costs.
Another advantage of gearmotors can be that having the right combination of engine and gearing can prolong design life and invite for the best power management and use.
Such problems are normal when a separate motor and gear reducer are connected together and lead to more engineering time and cost and also the potential for misalignment causing bearing failure and eventually reduced useful life.
Developments in gearmotor technology include the use of new specialty components, coatings and bearings, and also improved gear tooth styles that are optimized for sound reduction, increase in strength and improved life, all of which allows for improved performance in smaller packages. More after the jump.
Conceptually, motors and gearboxes can be blended and matched as needed to greatest fit the application form, but in the finish, the complete gearmotor may be the driving factor. There are many of motors and gearbox types that can be mixed; for example, the right position wormgear, planetary and parallel shaft gearbox can be combined with long lasting magnet dc, ac induction, or brushless dc motors.
